NASA's caption: On March 22, 2014, a rainfall-triggered landslide near Oso, Washington sent muddy debris spilling across the North Fork of the Stillaguamish River. The slide left an earthen dam that blocked the river, causing a barrier lake to form. The Operational Land Imager (OLI) on the Landsat 8 satellite acquired this image of landslide debris and the barrier lake on March 23, 2014.

The Operational Land Imager (OLI) on Landsat 8 acquired this image of landslide debris and the barrier lake on March 23, 2014. An image of the same area acquired on January 18, 2014, is shown in the following slide for comparison.
